ventilation in a vaulted cieling

I'm going to convert my screened porch to a 4 season room. It has a gable roof and is open to the living area. To properly insulate it, I was planning on vented soffit, ridge vent, insulation batts and ventilation baffles. How many baffles do I need? Between each rafter?

Also - do they need to go the length from soffit to ridge vent, or will one section at the bottom suffice?

The proper vent system will depend on how much & type of insullation. I recomend using a Smart Vent by DCI rather than soffit vents. It is not hard to install. It will cost more but is worth it in the long run. I manage a Large home improvement company and we use it all of the time. Email me and I will give you my phone number. I am more than happy to give you free advise over the phone. [email protected]

I checked out the website for smart vent and it looks like more work I'd rather not do. this job is a remodel - roof is already there. I don't think I want to rip off the lower row of shingles to put the vent in. It just seems I'm better off (effort wise) with traditional vented sofit.
